Abstract

A flat panel display comprises a substrate, a plurality of data lines, a plurality of scan lines, a source electrode driver element and a grid electrode driver element. The substrate comprises a pixel array. The plurality of data lines are electrically connected to the pixel array. The plurality of scan lines comprise p groups of scan lines and are electrically connected with the pixel array, and P is a positive integer. In the same group of the scan lines, at least partial scan lines are not adjacent. The source electrode unit is electrically connected to the partial scan lines. The grid electrode driver element comprises p shift register circuits which are respectively used to enable the p groups of scan lines. In a first picture frame period, the p groups of scan lines are enabled by a first group sequence; in a second picture frame period, the p groups of scan lines are enabled by a second group sequence, and the first group sequence is different from the second group sequence.

Description

【Technical field】 [0001] The present invention relates to a flat-panel display and a driving method thereof, in particular to a flat-panel display capable of improving image quality and a driving method thereof. 【Background technique】 [0002] Nowadays, the technology of flat panel displays develops rapidly, and various technologies are continuously developed. In order to reduce the number of integrated circuit (IC) signal lines to save costs, some non-traditional panel charging circuit architectures have emerged in the technical field of the present invention. However, in these panel charging architectures, since the circuit layout of each pixel is different from the traditional circuit layout, various traces (mura) will be generated on the picture, thereby affecting the image quality of the picture. [0003] Figure 1 is a schematic diagram of a conventional liquid crystal display. As shown in FIG. 1, the liquid crystal display 100 includes a substrate (not shown in the f...
